[0027] Embodiment 1,

It is detachably fixed between two frame beams 1 by bolts, and an adapted battery compartment 2 is loaded inside, including at least one layer of hoisting frame body 3. Figure 2 and Figure 3 As shown, the main body 3 of the hanging frame includes a plurality of first vertical plates 31, a plurality of supporting beams 32, two receiving longitudinal beams 33 and a plurality of second vertical plates 34, which are assembled and fixed to each other to form a two-layer frame structure, wherein the first vertical plate 31 is used to install the entire hanging frame main body 3 on the beam 1, as shown in FIG. Figure 4 As shown, the first vertical plate 31 is approximately in the shape of a right-angled triangle, and a mounting plate 35 is provided on the upper part facing the beam 1. The mounting plate 35 is fixedly arranged perpendicular to the plane where the first vertical plate 31 is located, and is integrally formed with the first vertical plate 31. The mounting plate 35 is parallel to the middle vertical plate of the beam 1; a reinforcing rib plate 36 is also provided between the mounting plate 35 and the first vertical plate 31 to enhance its strength; the mounting plate 35 is provided with upper connecting holes 351 arranged in a line vertically along its length direction, and correspondingly, the middle vertical plate of the beam 1 is also provided with bolt holes arranged in a line; the lower end of the first vertical plate 31 is provided with three lower connecting holes 311 arranged in a horizontal "品" shape. The first vertical plates 31 are provided with 6 in total, which correspond to the two beams 1 respectively, and are relatively fixed by bolts passing through the bolt holes and the upper connection holes 351, and two are symmetrically grouped; the lower ends of the two first vertical plates 31 in a group are fixed with a supporting beam 32 by bolts, referring to Figure 5 As shown, the supporting crossbeam 32 is an L-shaped angle steel, and the vertical plates at both ends are widened. The widened vertical plates are provided with long slot connection holes 321 that match the lower connection holes 311 at the lower end of the first vertical plate 31. They are also arranged in a horizontal "品" shape and can be adjusted and fixed to the lower end of the first vertical plate 31. The three groups of three supporting crossbeams 32 are arranged in a layer, parallel and flush with each other. Two supporting longitudinal beams 33 are installed on the upper side of the supporting crossbeam 32 in a vertical and horizontal manner, arranged at intervals, combined with Figure 6As shown, the receiving longitudinal beam 33 is also made of L-shaped angle steel. An opening groove 37 is provided at the junction of the receiving longitudinal beam 33 and the supporting cross beam 32, and its width is the same as the width of the transverse plate of the supporting cross beam 32, so that the receiving longitudinal beam 33 can just span and be clamped on multiple supporting cross beams 32, and a fixed connection is completed between the two. The distance between the vertical plates of the two receiving longitudinal beams 33 is just equal to the width of the battery compartment 2. A connecting through hole is further provided on the bottom plate of the receiving longitudinal beam 33. Square tubes are fixedly installed at the bottom of both sides of the battery compartment 2, and are installed and fixed by bolts passing through the square tubes and the connecting through holes on the receiving longitudinal beam 33.

[0029] The second layer located below is also fixedly formed by the supporting cross beam 32 and the receiving longitudinal beam 33, and is fixedly connected to the first layer through a plurality of second vertical plates 34. Figure 7 As shown, the structure of the second vertical plate 34 is similar to that of the supporting cross beam 32, but is arranged vertically. The second vertical plate 34 is also made of L-shaped angle steel. Connecting screw holes 341 are provided on the side wall for connecting to the lower end of the first vertical wall, and are also arranged in a horizontal "pin" shape, which is adapted to the lower connecting holes 311 at the lower end of the first vertical plate 31. The first vertical plate 31, the supporting cross beam 32 and the second vertical plate 34 are fixedly connected by bolts passing through the lower connecting holes 311, the connecting screw holes 341 and the long groove connecting holes 321 in sequence. Connecting screw holes 341 are provided at both the upper and lower ends of the second vertical plate 34.

[0030] In a further optimized technical solution, in order to prevent bumps during vehicle operation, fixing holes are provided on the transverse plate of the supporting cross beam 32, and the fixing holes are within the range of the opening groove 37 of the receiving longitudinal beam 33. Positioning bolts are installed in the fixing holes, and clamping plates are sleeved on the positioning bolts. The clamping plates play a role in clamping and fixing the receiving longitudinal beam 33. At the same time, damping gaskets are installed above the clamping plates, and the positioning bolts are fixedly installed through the countersunk heads at the tops of the damping gaskets, which not only avoids collision with the battery compartment 2, but also uses the damping gaskets to support and shock-absorb the battery compartment 2.

[0031] Embodiment 2

[0032] In order to be able to adapt to battery compartments 2 of different sizes, the receiving longitudinal beam 33 can be slidably adjusted and fixed relative to the supporting cross beam 32. Refer to Figure 8 and Figure 9As shown, an opening groove 37 is also provided at the junction of the receiving longitudinal beam 33 and the supporting cross beam 32. Guide plates 38 are respectively and fixedly installed at the bottoms of the front and rear edges of the opening groove 37. The guide plates 38 are perpendicular to the bottom plate of the receiving longitudinal beam 33. The distance between the two guide plates 38 is the same as the width of the transverse plate in the supporting cross beam 32, which can define the sliding direction of the receiving longitudinal beam 33. Correspondingly, a plurality of fixing holes are provided on the supporting cross beam 32. When the widths of the two receiving longitudinal beams 33 are adjusted to the width of the battery compartment 2, the receiving longitudinal beam 33 and the supporting cross beam 32 are relatively fixed by positioning bolts.

[0033] In a further optimized technical solution, when the battery compartment 2 is placed and fixed on the receiving longitudinal beam 33, the installation position of the battery compartment 2 is such that the side wall of the battery compartment 2 cannot be closely attached to the second vertical plate 34 on the side. Therefore, two installation through holes 342 are provided on the vertical side wall of the second vertical plate 34 facing the battery compartment 2. A resilient screw is inserted through each of the installation through holes 342. A pressing plate is fixedly installed at the inner end of the resilient screw close to the battery compartment 2. A spring is also sleeved on the resilient screw, and the spring is placed between the pressing plate and the vertical side wall of the second vertical plate 34. At the same time, the outer end of the resilient screw is provided with a thread, and a fastening nut is sleeved on the outside thereof. The pressing plate is pressed against the side wall of the battery compartment 2 by the elastic force of the spring, and the possible shaking of the battery compartment 2 during vehicle operation is offset by the spring.

[0034] Embodiment 3

[0035] An intermediate hoisting structure for an assembled hybrid vehicle battery compartment has the same technical solution as that described in Embodiment 1. The difference between the two is that only one long slot connection hole 321 is provided on the vertical plates at both ends of the supporting cross beam 32 at the lowest layer, and there is no need to provide a plurality of connection holes in a triangular shape. Correspondingly, only one connection screw hole adapted to the long slot connection hole 321 is provided on the lower side wall of the second vertical plate 34. The two are fixedly connected by bolts, which improves the assembly efficiency and reduces the cost.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", "linkage", "setting" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Certainly, the above description is not a limitation to the present utility model, nor is the present utility model limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present utility model should also fall within the protection scope of the present utility model.
